CANADA – Researchers at McMaster University have successfully created a packaging tray with the capability to detect dangerous pathogens such as Salmonella in packages of raw or cooked foods. 

This innovative technology provides real-time detection without the need to open the package, making it a valuable tool for producers, retailers, and consumers.

The development aims to streamline the detection process, eliminate exposure to contamination, and reduce the time and cost associated with traditional lab-based methods in food production.

The newly developed packaging tray by McMaster University introduces a breakthrough in food safety. By incorporating a “food-safe reagent” lining and an embedded sensor, the tray can detect the presence of Salmonella, allowing for immediate signaling of contamination.

Moreover, the technology is adaptable to test for other common food-borne pathogens like E. coli and Listeria, providing versatility and comprehensive protection.

Akansha Prasad, a researcher and co-lead author of the published paper in the journal Advanced Materials, emphasizes that this technology can benefit everyone involved in the food supply chain.

“We’re hoping this technology will save lives, money, and food waste,” he said.

By enabling swift identification of contamination, producers can take prompt action to prevent the distribution of unsafe food, protecting consumers and preserving the reputation of food brands.

Shadman Khan, another researcher, and co-lead author, underscores the team’s focus on developing a system that is reliable, quick, affordable, and user-friendly.

The tray design includes sloped sides that direct juices to a sensor embedded in a window at the bottom.

Without the need for additional lab work, users can simply scan the underside of the sealed package with a cell phone, instantly determining the presence of pathogens. This user-friendly approach enhances the accessibility and effectiveness of the technology.

The pathogen-detecting packaging tray developed by McMaster University has significant implications for food safety.

As further research and development progress, the technology holds the potential to revolutionize the industry by preventing foodborne illnesses, reducing costs associated with recalls, and enhancing consumer trust.

Continued advancements may expand the scope to detect additional pathogens, ensuring comprehensive protection across various food products.

The research conducted by McMaster University aligns with the broader global effort to enhance food safety measures.

Governments, regulatory bodies, and scientific communities worldwide are actively exploring innovative solutions to address foodborne illnesses and improve food security.

The pathogen-detecting packaging tray represents a significant step towards achieving these goals, complementing existing efforts in food safety management.
